Averaging all the models in one forecasting window

Hi ,
I like your web site and you mobile application a lot, specially the Compare window between different forecasting models,
As a suggestion ,
I think there is a need to add a single line to sum all the forecasting modes in one line , as an example if three models forecasting there is a a rain in specific 3h period but the fourth one did not we can take the average of the three models and put a single number representing the rain gauge ,
I think averaging all the models in one forecasting window can be useful.
